Abstract
The invention relates to a method for removing floccules in sesame oil, which comprises the following steps: adding a surfactant into sesame raw oil subjected to preliminary filtration, uniformly mixing, refrigerating, standing and filtering. The surfactant is food-grade sucrose fatty acid ester of which the HLB value is 3 or 5. The surfactant accounts for 0.1-0.5 wt% of the sesame raw oil. The method is easy and simple to operate, has the advantage of cheap and accessible surfactant, and greatly shortens the standing time in the sesame oil refining process. The sesame oil treated by the method can keep clear after being placed at low temperature or for a long time, and does not generate any floccule precipitate.
Description
Technical field
The invention belongs to sesame oil processing technique field, particularly throw out removal methods in a kind of sesame oil.
Background technology
Sesame oil is a kind of flavor grease that our people enjoys a lot, and its traditional mode of production is the ground sesameseed oil adopting water substitution to produce.Along with the development of modern science and technology and the improvement of technique, many sesame oil manufacturing enterprises all adopt the production technique such as hot moulding, press filtration.But no matter adopt which kind of production technique, all need to filter the operations such as clarification, condense at the bottom of bottle in long shelf-lives to avoid Oleum Sesami and occur throw out.
Although have employed the operations such as sedimentation and filtration, but along with the prolongation in storage time, the bottle end, still there will be flocculent aggregate sometimes, under low-temp storage condition, some sesame oil also there will be muddiness simultaneously, even there is cotton-shaped material to separate out from oil, thus reduce the quality of oil, affect the credit of food oils sometimes, serious quality problems even can be caused to cause query and the complaint of human consumer, bring bad impact to the sale of sesame oil and enterprise.
Summary of the invention
The object of the invention is to provide throw out removal methods in a kind of sesame oil, this method solves throw out or precipitation easily appear in existing sesame oil problem when low temperature or long-time storage, and to sesame oil local flavor and qualitative effects very little.
For achieving the above object, the present invention adopts following technical scheme:
Flocculation material removal methods in a kind of sesame oil, is specially: in tentatively filtered sesame crude oil, add tensio-active agent and mix, freezing leave standstill after filter.
Concrete, described tensio-active agent is food grade sucrose fatty acid ester, and HLB value is 3 or 5; The addition of tensio-active agent is 0.1-0.5% of sesame crude oil weight.
After adding tensio-active agent in sesame crude oil, it can be made to mix (stirring velocity is preferably 10-20r/min) in 50-80 DEG C of heated and stirred 40-80min, then in 0-5 DEG C of freezing standing 6-12h.
First the inventive method adds lipophilic surfactant and heated and stirred in sesame crude oil, tensio-active agent is fully contacted with the wax molecule etc. in oil, controls stirring velocity, can form multipolymer very well and then to separate out from oil simultaneously.Need freezing leaving standstill after heated and stirred mixing, the freezing sesame oil left standstill filters rapidly under cryogenic, and filtration temperature controls below 5 DEG C.
Traditional precipitation that sesame oil processing mainly adopts hydration degum, the long-time method left standstill removes or prevent throw out in sesame oil, but aquation can affect the fragrance of sesame oil, the standing throw out that can not remove well in sesame oil of long period, low temperature or long-time placement still can become muddy or have throw out to separate out.The inventive method utilizes the colloids such as wax in tensio-active agent and sesame oil to be easy to combine the characteristic forming multipolymer, realizes more fully promptly removing the colloids such as wax.Adopt the sesame oil of the inventive method process not muddy or generation throw out under long period, low temperature placement condition.
Compared to the prior art, beneficial effect of the present invention:
Removal methods of the present invention is simple, easy and simple to handle, and tensio-active agent is cheap and easy to get, also substantially reduces the time of repose in sesame oil refining process.Adopt the sesame oil of the inventive method process can less than when 5 DEG C, placement more than one month keep not muddy, do not have throw out to separate out yet.
Embodiment
The present invention is described further by the following examples, but protection scope of the present invention is not limited thereto.
embodiment 1
Flocculation material removal methods in a kind of sesame oil, be specially: in tentatively filtered sesame crude oil, add the food grade sucrose fatty acid ester (HLB value is 3) accounting for sesame crude oil weight 0.3%, it is made to mix (stirring velocity is 15r/min) in 50 DEG C of heated and stirred 60min, then in 4 DEG C of freezing standing 6h, then rapid filtration under 4 DEG C of conditions.
embodiment 2
Flocculation material removal methods in a kind of sesame oil, be specially: in tentatively filtered sesame crude oil, add the food grade sucrose fatty acid ester (HLB value is 5) accounting for sesame crude oil weight 0.1%, it is made to mix (stirring velocity is 10r/min) in 80 DEG C of heated and stirred 40min, then in 2 DEG C of freezing standing 10h, then rapid filtration under 2 DEG C of conditions.
embodiment 3
Flocculation material removal methods in a kind of sesame oil, be specially: in tentatively filtered sesame crude oil, add the food grade sucrose fatty acid ester (HLB value is 3) accounting for sesame crude oil weight 0.5%, it is made to mix (stirring velocity is 20r/min) in 60 DEG C of heated and stirred 80min, then in 3 DEG C of freezing standing 12h, then rapid filtration under 3 DEG C of conditions.
Adopt the sesame oil of above-described embodiment process in low temperature less than 5 DEG C, place one month, all not muddy, do not produce throw out yet.
Claims (3)
1. a flocculation material removal methods in sesame oil, is characterized in that, adds tensio-active agent and mix in tentatively filtered sesame crude oil, freezing leave standstill after filter.
2. flocculation material removal methods in sesame oil as claimed in claim 1, it is characterized in that, described tensio-active agent is food grade sucrose fatty acid ester, and HLB value is 3 or 5; The addition of tensio-active agent is 0.1-0.5% of sesame crude oil weight.
3. flocculation material removal methods in sesame oil as claimed in claim 1 or 2, is characterized in that, make it mix in 50-80 DEG C of heated and stirred 40-80min, then leave standstill 6-12h in 0-5 DEG C.
